Java programmers in the industry, there are a lot of Java developers the ideal is to become a good Java Architect, Java architect's main task is not engaged in the preparation of specific software programs, but in the framework of a higher level of development work . He must be well aware of the development of technology, and the need for good organization and management skills. It can be said that a good or bad job Java architect determines the success or failure of the entire software development projects. Java architect So what needs to master the knowledge of it? Now, let me tell Java architects need to have knowledge of these points!
1, source code analysis framework
Design Patterns: Singleton Singleton, Factory factory pattern, Proxy proxy mode, Template template mode, Prototype prototype mode
Spring5: Spring reminded structure, IOC injection principle, AOP design principles, Spring transaction processing mechanism, SpringMVC, Spring source code analysis.
Mybatis: Mybatis architecture, Mybatis core application and configuration, Mybatis related queries, integration with Spring, Mybatis source code analysis.
2, performance optimization
JVM performance optimization: analysis of the overall structure of JVM, Detailed garbage collection GC, JVM performance tuning and troubleshooting tool
Tuning Nginx: Nginx project architecture, Nginx core configuration, Nginx configuration algorithm load
Tuning Tomcat: Tomcat operational mechanism and framework, Tomcat threading model, Tomcat Performance Tuning
MySQL Performance: SQL execution plan, AQL optimization, index optimization.
3, master cell technology
Object pooling, connection pooling, thread pooling, Java reflection technology, write the necessary technical framework, but there are serious performance issues, alternative Java byte code technology.
4, master nio, is worth noting that "direct memory" features, usage scenarios.
5, master multi-threaded Java synchronous asynchronous.
6, to master a variety of Java implementation principle of a collection of objects, these tools will make you choose the right data structures in solving problems, and efficient problem solving.
7, skilled use of data structures and algorithms, array, hash, list, sort tree ...... word is either space or time for a space for time.
8, tcp familiar with the agreement, the entire process to create a three-way handshake connection and disconnect the four-way handshake, do not understand the words, do not be optimized for high concurrent network applications.
9 familiar with http protocol, especially http head, I found a lot of work for more than five years are unclear session cookie and the life cycle and the association between them.
10, familiar with the system clustering, load balancing, reverse proxy, static and dynamic separation, static website.
11, master distributed.
Java concurrent programming and network programming: Java thread state, the thread pool thread communication, thread-safe, Netty high-performance principle
Distributed development framework: Distributed Systems mouth call technology: RPC, Zookeeper principle and application of Apache distributed systems, design and application of Ali Dubbo
Distributed Middleware: distributed server management, distributed messaging, distributed data caching, MongoDB enterprise clustering solutions
12, to master the design capabilities of the database, its basic parameter optimization, slow query log analysis, master-slave configuration replication, to be at least half mysqldba.
That is all I sort of Java architects need to know some knowledge points. In order to achieve a qualified architect Java, need skills system is very large, not to say that only bragging, but in a real complex business scenarios, can be a good tease out a solution, to meet system requirements. As mentioned above: Java Getting started is simple, but can go far, you have to see yourself, so-called "master the introduction of the door, the practice of personal." So remember: do something right are always envious of people high wages, the whole of China does not lack talent, if you want to have in the Java space their own one day, then you are ready to work hard.
